KEEPING THE EDGE

KEEPING THE EDGETo pull a nail from which the bonnet is recessed in the wood, hit it from the opposite side. However, its edge is hopelessly blunted.

If the need arises frequently, is to make a small device — a metal plate with stepped holes: pulled right on the tip of the nail, can be beat not by him, but for the die, and the nail will remain sharp.
